MO SEL VITELIC
Bidirectional Mode
Data buffering between two systems can be
achieved by pairing two FIFO arrays as shown in
Figure 6. This allows each system to READ and
WRITE shared data. The FULL FLAG (FF) must be
monitored on the FIFO where WRITE ENABLE (W)
is used and the EMPTY FLAG (EF) must be
monitored on the FIFO where READ ENABLE (R) is
used. Both Width Expansion and Depth Expansion
Modes may be used in combination with
Bidirectional Mode.
Compound Expansion Mode:
Both Width Expansion Mode and Depth
Expansion (Daisy Chain) Mode can be used
together to configure a large FIFO array (See
Figure 4 and 5).
